A hybrid PVD process is being developed with ion implantation to imbed a layer of material below the surface of the piece part. Figure 1 shows this concept. This concept provides an excellent bond layer for a coating applied by the PVD process. Titanium ions are implanted to improve adhesion and boron ions are used to reduce friction. Coatings to be evaluated are listed in Table 7.

CVD-PVD Coating Materials To Be Evaluated For Adherence And Wear Resistance Are Shown Below.
